Description

I've been working on implementing Microsoft Graph webhook subscriptions in my application, and I've run into an issue with subscription validation. Whenever I attempt to validate the subscription, I've consistently receive the following error message:

GraphError: Subscription validation request timed out.

My subscription server is deployed and hosted on Google Cloud Function v2, allowing all unauthenticated invocations.

The following verification is performed using Microsoft's Postman Collection:

  • Endpoint is accessible on the internet with unauthenticated invocation
  • Endpoint is returning 200OK, text-plain, decoded validationToken as intended
  • Endpoint able to reply within 10s timeframe consistently

However, when I actually attempt to create subscription request using MicrosoftGraph Javascript SDK, the validation request always faces timeout issue despite it being accessible via PostMan.

Code Snippet to Invoke Subscription Request

const requestBody: Subscription =
        changeType: "updated",
        resource: `/users/${folderId}/drive/root
        expirationDateTime: new Date(now.setDate(now.getDate() + 28)).toISOString(),
        notificationUrl: `${process.env.ONEDRIVE_URL}/folders/${folderId}?workspaceId=${workspaceId}`,
        clientState: "somerandomtext";
      }

await driveClient.api("/subscriptions").post(requestBody);

Console Errors:

GraphError: Subscription validation request timed out.

Code Snippet to Listen for Subscription Validation

import { FastifyPluginAsyncTypebox } from "@fastify/type-provider-typebox";

import { Type } from "@sinclair/typebox";

export const ParamsSchema = Type.Object({
  fid: Type.String(),
});

export const QuerySchema = Type.Object({
  workspaceId: Type.RegEx(/^[0-9a-z]{25}$/),
  validationToken: Type.Optional(Type.String()),
});


const main: FastifyPluginAsyncTypebox = async (app, options): Promise<void> => {
  /**
   * Listens to changes to a folder
   */
  app.post("/", { schema: { params: ParamsSchema, querystring: QuerySchema } }, async (req, rep) => {
    app.log.info("Received webhook request");
    // If there is a validationToken parameter
    // in the query string, this is the endpoint validation
    // request sent by Microsoft Graph. Return the token
    // as plain text with a 200 response
    // https://docs.microsoft.com/graph/webhooks#notification-endpoint-validation
    // https://github.com/microsoftgraph/nodejs-webhooks-sample/blob/main/routes/listen.js#L13
    if (req.query.validationToken) {
      return req.query.validationToken;
    }

    // Other logic but is commented
    return {};
  });
}

SDK Version - 3.0.7

  • Node (Check, if using Node version of SDK)

Node Version - v18.17.1

I'm unsure why the validation request fails in my application but works with Postman. Can anyone offer guidance on what could be causing this issue or suggest potential solutions?

That's a good question. Can you run it locally via Dev Tunnels or ngrok? Can you create your subscription via Postman vs. just calling your validation endpoint? This would also be helpful. Thanks!
